+# Docker container for hubPredEvalsData generation
+
+This docker container is a wrapper around
+`hubPredEvalsData::generate_evals_data()` and hosts the in-development code
+from
+[hubverse-org/hubPredEvalsData](https://github.com/hubverse-org/hubPredEvalsData),
+which is used to generate tables of evaluation data from a hub's [oracle
+output](https://hubverse.io/en/latest/user-guide/target-data.html#oracle-output).
+
+The image is built and deployed to the GitHub Container Registry (https://ghcr.io).
+You can find the [latest version of the
+image](https://github.com/hubverse-org/hubPredEvalsData-docker/pkgs/container/hubpredevalsdata-docker/340871974?tag=main)
+by using the `main` tag:
+
+From the command line:
+
+```sh
+docker pull ghcr.io/hubverse-org/hubpredevalsdata-docker:main
+```
+
+## Usage
+
+The main usage for this image is a step in [the hub dashboard control
+room](https://github.com/hubverse-org/hub-dashboard-control-room) that builds
+evals data if it exists.
+
+The container packages the `create-predevals-data.R` script, which will display
+help documentation if you pass `--help` to it.
+
+```sh
+docker run --rm -it \
+-v "$(pwd)":/project \
+ghcr.io/hubverse-org/hubpredevalsdata-docker:main
+create-predevals-data.R --help
+```
+
+````
+Calculate eval scores data and a predevals-config.json file
+
+USAGE
+
+   create-predevals-data.R [--help] -h </path/to/hub> -c <cfg> -d <oracle> [-o <dir>]
+
+ARGUMENTS
+
+  --help             print help and exit
+  -h </path/to/hub>  path to a local copy of the hub
+  -c <cfg>           path or URL of predevals config file
+  -d <oracle>        path or URL to oracle output data
+  -o <dir>           output directory
+
+EXAMPLE
+
+```bash
+prefix="https://raw.githubusercontent.com/elray1/flusight-dashboard/refs/heads"
+cfg="${prefix}/main/predevals-config.yml"
+oracle="${prefix}/oracle-data/oracle-output.csv"
+
+tmp=$(mktemp -d)
+git clone https://github.com/cdcepi/FluSight-forecast-hub.git $tmp
+
+create-predevals-data.R -h $tmp -c $cfg -d $oracle
+```
+````
+
+## Updating
+
+Because hubPredEvalsData is constantly improving, this container needs to be
+rebuilt with the updated version. This can be achieved by running the update
+script:
+
+```
+./scripts/update.R
+```
+
+When the update is complete, if there are updates, then the lockfile will change
+and you will need to commit it. Once you commit and push, the docker image will
+be rebuilt.
